While
the
cost
of
building
a
network
of
high-voltage
electricity
lines
spanning
the
North
Sea
“could
be
very
high”,
doing
so
would
cut
by
25%
the
price
tag
of
linking
up
offshore
wind,
wave
and
tidal
farms
to
the
onshore
grid,
according
to
Parliament’s
Energy
and
Climate
Change
Committee.
The
supergrid
would
reduce
the
strain
being
imposed
on
the
UK’s
ageing
onshore
grid,
and
allow
the
country
to
flip
from
being
a
net
importer
of
energy
to
a
net
exporter
–
perhaps
in
as
little
as
a
decade.
Perhaps
most
importantly,
says
committee…
